KEY MESSAGES

- Pleasant, mainly dry weather is forecast through the period with near to above normal temperatures.

SHORT TERM /THROUGH MONDAY/

Issued at 133 PM CDT Sun Oct 4 2026

Dry conditions, under clear skies, will continue through the day Monday (and beyond!) as a 1026 mb area of high pressure system over the central Plains early this afternoon slides eastward, taking control over the region. Ahead of it, north-northwest winds this afternoon will continue, with a few gusts up to 20 knots possible before winds become light and variable tonight. Light winds and clear skies should support a cool night, with lows falling to middle to upper 40s for much of the area. Seasonal temperatures are expected Monday, warming to the middle to upper 60s.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/

Issued at 133 PM CDT Sun Oct 4 2026

The dry weather pattern will continue through at least Wednesday this week as the aforementioned high pressure system will linger over the central Great Lakes for the early part of the work week. By Tuesday, the upper-level flow will become more zonal, with strengthening southerly return flow around the high. Southwesterly surface flow will support increasing warm air advection, resulting in high temperatures rising to the lower to middle 70s for Tuesday and Wednesday. The main focus for adjustments for this latest forecast was to lower the forecast dew points Monday through Wednesday, considering the consensus blends tend to underperform on the PBL mixing in dry air masses. Ultimately, this will result in lower relative humidity.

Our lone chance of any precipitation looks to come on Thursday night, when a weak shortwave in the mid-levels is progged to approach the region. Mesoscale forcing will be enhanced due to a warm frontal zone draped over Iowa. With the drier air in place, chances of measurable rainfall remain low, with both the NBM and LREF probabilities of measurable rain only around 10-30%. Outside of this precip chance, dry conditions should prevail this week.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1211 PM CDT Sun Oct 4 2026

VFR conditions are expected throughout the TAF period, under abundant clear skies as high pressure builds in tonight/Monday. This afternoon, there could be some breezy north-northwest winds, with gusts up to 20 knots, but winds should go light after sunset as the high builds in.
